Abstract
Description
- This application Claims the benefit of U.S. Provisional Application No. 60/924,764 filed May 30, 2007.
- The present invention relates to a humidity control system and in particular to a humidity control unit which utilizes low grade waste heat to aid in regeneration of a desiccant device.
- Various systems have been proposed for providing air handling systems which maintain humidity levels in indoor facilities in a comfortable range. Certain of these systems have been particularly designed for use in ice arenas in which an ice surface is maintained at freezing temperatures or other applications such as cold storage facilities in which waste heat is available from a large ice plant. Such systems typically use a liquid refrigerant loop which is cooled by a primary refrigerant system of the direct vaporization type. Such systems are shown for example in U.S. Pat. No. 6,321,551 in which a dehumidifier unit connected to the ice rink coils is used to dry process air. Another such system is disclosed in U.S. Pat. No. 6,935,131 which supplements the dehumidification unit in the process air stream with a reheat coil coupled to a waste heat line from the compressor of the primary refrigeration unit. This reheat coil heats regeneration air being supplied to the regeneration section of a desiccant wheel to increase the desiccant media's capacity to remove further moisture from the process air stream. This reheat coil system is used with a dehumidification coil in the process air section of the dehumidification system which is connected to the liquid refrigeration system.
- In accordance with an aspect of the present invention a reactivation circuit is provided for preheating regeneration air supplied to a desiccant unit of a dehumidification system. The reactivation circuit consists of a reactivation air cooled condenser coil/dehumidifier coil connected to a direct vaporization refrigeration circuit including a compressor and refrigerant heat exchanger (using water, brine, or other refrigerant) functioning as the evaporator for the circuit. This reactivation circuit functions as a water source heat pump to extract heat from the liquid refrigerant in a secondary refrigeration circuit that freezes the ice sheet. Low grade (low temperature 85-95 degrees F.) heat is rejected from the secondary refrigeration plant and extracted by the reactivation circuit to generate a higher grade heat (high temperature 115-130 degrees F.) through the air cooled condenser coil to regenerate the desiccant material. The heated air drives moisture from the desiccant and is discharged to the atmosphere.
- In accordance with another aspect of the invention return air, or return air and fresh air, circulated to the interior space or enclosure containing the ice rink or the like is dehumidified in a continuous process by the desiccant material. Preferably the desiccant is a desiccant wheel which rotates through both the supply process air stream and the reactivation air stream. A dehumidification coil is positioned in the reactivation air stream upstream of the regeneration section of the dehumidifier wheel and is connected to a direct vaporization refrigeration circuit having a series of compressors and then to a separate air cooled condenser coil. By this system, if the enclosure humidity level increases, and the return air and/or combination of return air and fresh air humidity is above a predetermined level, the second stage compressor will be energized to cool and dehumidify the air before it reaches the desiccant wheel. Third and fourth stage compressors also are successively energized if the humidity of the air entering the desiccant continues to rise. When the return air humidity is returned to its controlled set point, the compressors stage off in the reverse order and the dehumidifier is eventually de-energized.
- In a more generalized embodiment of the invention the refrigeration circuit which generates the heat for the condensing coil which heats the desiccant regeneration or reactivation air stream is coupled with any low grade liquid heat loop that is decoupled from atmospheric temperature. This means a system which is not bound to atmospheric conditions and allows for control of suitable reactivation temperatures independent of ambient atmospheric temperatures. Accordingly the water, glycol or brine loop need not be limited to the heat rejected from secondary refrigerant loop such as the ice sheet cooling system above, but will include known solar heat loops, cooling tower, ground water loops, other heat of rejection cooling loops, or any loop that is designed to be maintained at a temperature between 45° F. and 95° F. year round. For example a low grade solar heat loop using water heated by the sun at low temperatures could be used.
- The above and other objects, features and advantages of the present invention will become apparent from the following detailed description of an illustrative embodiment which is to be read in conjunction with the accompanying drawings wherein:
-
FIG. 1 is a schematic diagram of a dehumidifier system in accordance with the present invention; and -
FIG. 2 is a more detailed schematic view of one of the refrigeration systems used in the invention. - As seen in
FIG. 1 , thesystem 10 of the present invention includes arefrigeration system 12 for freezing anice sheet 14 located within an enclosed space or building (not shown).System 10 further includes ahumidity control unit 16 operable to control the humidity of areturn air stream 18 coming from the enclosure and being returned thereto by the operation of afan 20. If required, some proportion of fresh air can be introduced through aduct 22 in known manner into the return air stream. - The
refrigeration system 12 includes a liquid refrigerantsecondary refrigeration system 24 which includes a set of coils (not shown) located in the floor of the ice rink orice plant 14 or the like and connected by supply andreturn lines pump 29 to anevaporator 30. -
Evaporator 30 forms a part of aprimary refrigeration system 32 which includes acondenser 34 and acompressor 36 connected bylines 38 to a coil within theevaporator 30. The primary refrigeration system is a conventional direct vaporization system which absorbs heat from the liquid refrigeration system in the evaporator and discharges that heat in thecondenser 34 to the atmosphere. Theprimary refrigeration system 32 includes anadditional heat exchanger 40 connected bylines refrigerant line 38. This heat exchanger functions as an evaporator for athird refrigeration system 50 which is also a direct vaporization refrigeration system. Thesystem 50 includes acompressor 52 located in thehousing 54 of thehumidity control device 16. That device includes aregeneration air duct 56 and processair duct 58 separated from each other by conventional walls and baffling. -
Dehumidification system 16 also includes adesiccant wheel device 60 of known construction rotatably mounted in the housing such that it is regenerated in theregeneration duct 56 and dehumidifies air in theprocess air duct 58. The desiccant wheel is of known construction and rotatably mounted in any known manner. - Regeneration air is drawn into the
regeneration duct 56 from the atmosphere through anopening 62 in thehousing 54 by afan 64 which discharges the regeneration air, after it passes through the desiccant wheel, to the atmosphere. - The
refrigeration system 50 includes acondenser coil 66 mounted upstream of the desiccant wheel in theregeneration conduit 56. The coil is connected byrefrigerant lines 68 to thecompressor 52 which is in turn connected bylines 70 to theheat exchanger 40. - When it is necessary to dehumidify return air and/or return and fresh air being supplied to the interior of the enclosure, the
compressor 52 is operated and supplies cooled refrigerant from the condenser to theheat exchanger 40. The temperature of the coolant inline 70 is raised in the heat exchanger 40 (by the coolant inlines 38 flowing from theline 42 throughheat exchanger 40 to line 44) and returned to thecompressor 52 where the refrigerant is compressed, heated and supplied to thecondenser coil 66. In the condenser coil the refrigerant is cooled by the supply air entering theduct 62 and transfers heat to the regeneration air which then enters the regeneration portion of the rotatingdesiccant wheel 60 before being charged to the atmosphere. As a result, some of the low grade heat (from the liquid inloop line 68 at 105° F. to 135° F.) through the air cooled condenser coil to regenerate the desiccant wheel. This heated air drives the moisture from the desiccant and regenerates it. It also contributes to cooling of the refrigerant insystem 32. - The above dehumidification process is continuous as the desiccant wheel rotates through the supply and reactivation air streams. However, if the rink humidity level rises above a predetermined point, requiring additional dehumidification, the
humidity control device 16 is arranged to provide additional dehumidification, before the return air and/or fresh air/return air pass through the desiccant wheel. As seen most clearly inFIG. 2 , to accomplish this, the dehumidifier includes anadditional refrigeration circuit 80 connected tomultiple compressors lines 86 to adehumidification coil 88 and to an air cooledcondenser coil 90 mounted at one end of thehousing 54. Thus, when additional dehumidification is required, beyond what the desiccant wheel can provide by itself, thecompressor 82 is operated to supply compressed refrigerant to the dehumidification coil which removes moisture from the air before it enters the desiccant wheel device. At the same time it cools the air before it reaches the desiccant wheel. The heat absorbed from the air in the dehumidification coil by the refrigerant is discharged to the atmosphere in thecondensation coil 90 which is cooled by thefans 92, and returned to thecompressor 82. If still further dehumidification is required, the second andthird stage compressors - As seen more clearly in
FIG. 2 , therefrigeration circuit 80 is actually three independent refrigeration circuits which use different sections of thecoils compressor 82 is connected bylines 82′ tocoil sections 88′ and 90′;compressor 83 is connected bylines 83′ tocoil sections 88″ and 90″ andcompressor 84 is connected bylines 84′ tocoil sections 88″′ 90″′. Each circuit is separately energized as required. and By cooling and dehumidifying the return air before it enters the desiccant wheel in this way the capacity of the desiccant wheel to remove further moisture from the process air stream in increased and the return air is reheated by the wheel to the desired process return temperature. - If desired or necessary some or all of the process air can be made to bypass the desiccant wheel using
appropriate duct work 100 as is known in the art. Also, appropriate temperature and humidity sensors and related controls are provided to selectively activate the various compressors as would occur to those skilled in the art. - Accordingly, the system provides sufficient capacity to handle varying conditions and variable amounts of make up air without modifying the
basic refrigeration systems - Although illustrative embodiments of the present invention have been described herein in detail in connection with the accompanying drawings, it is to be understood that the invention is not limited to those precise embodiments but that various changes and modifications may be effected therein by those skilled in the art without departing from the scope or spirit of this invention.
